Referring now more particularly to Fig. 1 of the drawings there isillustrated a printing business machine I00 incorporating the featuresof the present invention. The illustrated embodiment of the machine IIIis in the' form of an automatic printer or typewriter of thetype knownas the electromatic typewriter having the general construction andarrangement shown in U. 8. Patent No. 1,777,055, Russeli G. Thompson,granted September 30, 1930.

, The machine llil comprisesanupper main" frame II, a, connected lowersubframe ill hous-- ing the power mechanism, a movable carriage I03 anda plurality of type levers Ill. The power nets.

mechanism comprises the usual operating motor, power roll, clutchmechanism between the power 'roll and the type levers I04 and aplurality of operating keys. The subframe comprises casing structure I05receiving the operating motor; while the main frame IOI supports aremovable type hood I06 protecting .the type levers I04.

Also the main frame IOI carries a plurality of operating magnets adaptedto control the associated operating keys and supports a removable magnethood I01 protecting the operating mag- The carriage I03 comprises theusual assembly including spaced-apart end walls I08 rotatably supportinga removable platen roll I09 provided with a resilient covering, formedof rubber or the like, and cooperating with the type levers I04.

f Further the machine 100 comprises paper supporting and guidingmechanism H and paper cutting mechanism III, both carried by thecarriage I03, and paper position testing mechanism II2 carried by thesubframe I02.

Referring now more particularly to Figs. 1 to 3, inclusive, of thedrawings, the carriage I03 is supported by the main frame I 0| uponstructure including the rear carriage rail H3 and comprises a marginalstop rack II4 extending between the ends walls I08. The marginal stoprack carries two adjustable marginal stops. H5 and H6; while the rearcarriage rail II3 supports a fixture II'I upon which a tabulating leverI I8 is pivotally mounted by a pin I19. The tabulating lever II8 carriesan inturned projection I movement toward and away from the rear carriagerail II3. As viewed in Fig. 2, the tabulat-- ing lever H8 is biasedtoward the left by a coil spring I2I extending between the fixture Illand the tabulating lever H0, and also in a clockwise direction about thepin II9 by an arrangement comprising a rocking lever I22 pivotallymounted by a screw I23 upon the rear carriage rail- I I3. Moreparticularly, the rocking lever I22 rests upon a plate I24 fixed to thetop surface of the rear carriage rail H3 and comprises two arms I25 andI26. The lever I22 is biased in a counterclockwise direction about thescrew I23, as viewed in Fig. 2, by an arrangement comprising a coilspring I21 surrounding the screw I23 and extending between the plate I24and the arm I26; the arm I25 of the lever I22 being provided with anupstanding projection I28 engaging a leaf spring I secured to' theadjacent end of the tabulating lever IIO. At this point it is notedthatthe arm I of the lever I22 carries an upstanding dog I30 whichcooperates with a part of the paper cutting mechanism III, in a mannermore-fully explained hereinafter.

Also associated with the right-hand end of the tabulating lever II8,- isa bell crank I3I pivotally supported upon the main frame IM and frameml. The bell crank I3I may be moved against the bias of the coil springI32 toward the end of the tabulating lever IIB, thereby to rock thetabulating lever II 8 in the counterclockwise direction about the pinIIB, as viewed in Fig. 2, under the control of a strap I33 securedthereto; the strap I33 being operated by the power roll of the machineI00 when the tabulating operating key is actuated by the associatedoperating magnet. Further the rear carriage rail II3 carries a latch I34 which is pivotally mounted upon a pin I35 and biased toward anabutment I36 formed on the left-hand end of the tabulating lever II8.Further it is noted that the left-hand end of the tabulating 1 lever IIOcarries an abutment I31 which also pies its right-hand marginalposition, as viewed 7 from the front, as determined by the position ofthe righthand marginal stop I I5 upon the associated marginal stop rackII4. As the operating magnets are selectively energized thecorresponding operating keys are actuated, whereby' the correspondingtype levers I04 are selectively clutched to the power roll, assumingthat the operating motor is running. As each type lever I04 is clutchedto the power roll it is operated toward the platen roll I09 intostriking engagement with the paper stock carried thereby in order tocause the associated type character to be printed thereon. The typelever is then automatically declutched from the power roll and isreturned to its normal position; whereupon the carriage I03 is moved onespace toward the left.

When the return and line space operating magnet is energized theassociated operating key is actuated, whereby the carriage return andline space mechanism is first clutched to and then declutched from thepower roll in order to cause the carriage I03 to be returned to'itsnormal right-hand marginal position, as determined by the position ofthe right-hand marginal stop I I5 upon the marginal stop rail I I4, andto cause the platen roll I 09 to be line spaced.

When the tabulating magnet is energized the associated tabulatingoperating key is actuated, whereby the tabulating mechanism is firstclutched to and-then declutched from the power roll, whereby the strapI33 is operated in order to cause the bell crank I3I to be pivotedagainst the bias of the coil spring I32 into engagement with theright-hand end of the tabulating lever IIB. When the right-hand end ofthe tabulating lever H8 is thus depressed by the bell crank I3I thetabulating lever H0 is rocked in the counterclockwise direction aboutthe pin H9, as viewed in Fig. 2, against the bias of the rocking leverI22. Also when the tabulating lever H8 is rocked in the counterclockwisedirection about the pin Hi! the latch I34 rides behind the abutleft, asviewed from the front of the machine 4 I00. Also at this time therocking lever I22 is rotated in the clockwise direction about the screwI23, as viewed in Fig. 2, against the bias of the coil spring I21 due tothe action of the leaf spring .I29 carried by the left-hand end of thetabulating lever II8 upon the upstanding projection I28 assume 3 carriedby the arm' I25 of the rocking lever I22. When the rocking'lever I22 isthus rotated in the clockwise direction the upstanding dog I50 carriedby the arm.- I25 thereof is moved toward the platen roll I intocooperating relationship with respect to the paper cutting mechanismIII, in a manner more fully explained hereinafter.

When the carriage I02 is moved toward the left, as viewed from the frontof the machine I00, to its left-hand marginal extremity, the left-handmarginal stop I I5 carried by the marginal stop rack I I4 engages theinturned projection I25 carried on the left-hand end of the tabulatinglever H0; whereby the tabulatirlg lever H0 is moved toward the right,'asviewed in Fig. ,2. When the tabulatin lever H0 is moved toward theright, as viewed in Fig. 2 against the bias of the coil spring I2I, thepin II9 permitting this movement of the tabulating lever IIO aspreviously noted, the latch I34 rides from behind the abutment I35provided on the left-hand endof the tabulat ing lever I I0. When thelatch I34 rides from behind the abutment I36 provided on the left-handend of the tabulating lever II8, thereby unlatchin the same, thetabulating lever H8 is rotated in the clockwise direction about the pinII 9, as

viewed in Fig. 2, due to the bias exerted on the leaf spring IEQ carriedon the left-hand end thereof by the upstanding projection I28 carried onthe arm IE5 of the rocking lever I22. More particularly, the rockinglever I22 is rotated in the counterclockwise direction about the screwI23,

as viewed in Fig. 2', by the coil spring I21; where-. by the upstandingdog it0 carried by the arm' I25 of the rockin lever I22 is moved out of00 arms I55 constitute a support for the paper cutting mechanism III andcarry two screws I55 by means of which themechanism III is removablysecured in place. More particularly, two aligned notches I51 are formedin the side flanges I55 of the body I 53 and receive the center portionof the supporting bracket I50, while the center portion of thesupporting bracket I54 engages the rear wall of the body I55; the bodyI55 and the brackets I50 and I54 being removably secured in assembledrelation by two screws I55. More specifically, the two screws I55 extendthrough two spaced-apart holes provided in the supporting bracket I50and are threaded into aligned tapped holes provided in the supportingbracket I 54; whereby the body I52 is securely clamped between thebrackets I50 and I54. Thus it will be understood that a narrow upwardlyextending passage is formed between the bottom wall of the body I53 andtheadjacent wall of the bracket I 50 and between the side flanges I 55in order to receive and guide the ribbon of paper stock from the rollI60.

Further the mechanism 0 comprises a paper tensioning element I59including a base plate I15 and a substantially L-shaped inwardlydisposed leaf spring member I1I secured together by a plurality ofrivets or the like H2. The lower operating engagement with respect tothe paper v cutting mechanism III, for a purpose more fully explainedhereinafter. At this time the return and line space operating magnet maybe again energized in order to effect the return of the carriage I03 toits normal right-hand marginal extremity, in the manner previouslyexplained.

Y a substantially horizontal and inwardly disposed wall I54. Also thebody I50 comprises side flanges I55, the lower ends-of which terminatein out wardly and downwardly extending arms I55 arranged insubstantially parallel spaced-apart re' lation. A shaft I51 extendsthrough openings provided adiacentthe outer ends of the arms I55 and isprovided'with removable knurled thumb nuts I50 threaded on. the oppositeends thereof; the shaft I51 being adapted to support the spool I55 of arollof ribbon-like paper stock I50. Also a substantially channel-shaped"plate I5I is secured to the lower surface of the wall I54 by a number ofrivets I 52, the plate I5I having nostanding side flanges I55. The sideflanges I52 of the plate ,I5I constitute a continuation of the sideflanges I 55 of the body I52; whereby a smooth guide channel is providedfor the ribbon of paper stock from the roll I55:

upwardly and inwardly I55 arranged in parallel spaced-apartrelation. The

may be lifted and pulled rearwardly in order'to loosening the thumb nutI15 in an obvious I end of the base plate I10 is provided with aninwardly directed flange I13 which overhangs two aligned andspaced-apart pins I14 carried by the side flanges I55; thereby toprovide a pivotal mounting for the lower end of the paper tensioningelement I69. Also arearwardly extending screw I15 is fixed tothe bracketI50 and extends through an opening formed in the base plate I10; 'theopening formed in the base ,plate I15 comprising an enlarged centralhole I15 and a connecting restricted slot I11. Further the outerend ofthe screw I 15 carries a thumb nut I15 which engages the base plate I10.This arrangement permits ready removal of the paper tensioning elementI50 when the thumb nut I15 is suflieiently loosened due to the fabt thatthe thumb nut I18 will pass through the hole I15 formed in the baseplate I10 incident to lifting of the base plate I10. More specifically,when the thumb nut I18 is loosened the base plate I15 cause the inwardlydirected flange I10 to disengage the pins I14; whereby the thumb nut I15may be passed through the hole I15 formed in the base plate I10, in anobvious manner.

Further it will be understood that the leaf spring member I" engages theribbon of paper stock adjacent the knee between the body I55 and thewall I54, thereby to tensionthe ribbon of paper stock; the amount oftensioning thereof depending upon the pressure exerted upon the papertensioning element I 50, which in turn may be oppositely determined bytightening and manner.

1 Referring now more particularly to Figs. 1 and 6 to 10, inclusive, ofthe drawings. it is noted that the paper cutting mechanism III comprisesa substantially channel-shaped base 255 having downwardly turned sideflanges 25I and an elongated rearwardly and downwardly extending paperchute 252 having upwardly turned side ,flaliges 202; the base 250 andthe paper chute 252 being suitably secured together by rivets-or thelike. The base 255 is secured tothe twoarms I55' of-the' supportingbracket" I54 by means of the two screws I55 andtwo thumbnuts254'threaded the front end of the paper chute 202 terminatesadjacent the rear edge of the slot 206 formed in the base'200 and thatthe paper guiding struc-- ture is secured to the base 200 adjacent thefront edge of the slot 206 formed therein by rivets or the like. Moreparticularly, the paper guiding structure comprises a bottom wall 201having a downwardly and forwardly extending lip 208 and a top plate200-having downwardly turned side flanges 2 ID. The paper guidingstructure secured to the base 200 forwardly of the slot 206 formedtherein and thepaper chute 202 secured to the base 200 rearwardly of theslot 200 formed therein are arranged in alignment, whereby the ribbon ofpaper stock coming from the platen roll I09 of the machine I is fedthrough the paper guiding structure and across the slot 206 formed inthe base 200 and into the paper chute 202.

More particularly, the top wall 209 and the bottom wall 201, inconjunction with the side flanges 2|0, form a narrow guide channel forthe ribbon of paper stock; this channel having an enlarged receivingopening adjacent the platen roll I00 of the machine |00 due tothearrangement of the downwardly directed lip 208 carried by the bottomwall 201. Also a guide plate 2 is secured to the base 200 above thepaper guiding structure by an arrangement comprising two screws 2|2extending through holes provided in the guide plate 2 and threaded intoaligned tapped holes provided in the base 200. The guide plate 2 isretained in position above the paper guiding structure due to theprovision of two hollow spacing columns 2|3 surrounding the screws 2|2and interposed between the base 200 and the guide plate 2| Further theguide plate 2 comprises a downwardly and rearwardly turned flange 2which extends into the paper chute 202 between the side flanges 203;thereby positively to guide the ribbon of paper stock over the slot 206formed in the base 200 and into the paper chute 202.

Further the paper cutting mechanism comprises a movable knife support2|! including two parallel, vertically spaced-apart supporting rods 2|6extending through two pairs of aligned holes 4 provided in the sideflanges 2M 01' the base 200;

the two pairs of aligned holes provided in the side flanges 20| of thebase 200 being disposed slightly rearwardly. of the slot 206 formedtherein. Accordingly the movable knife support 2| 5 is slidablysupported by the side flanges 20| of the base 200 slightly rearwardly ofthe slot 206 formed therein. The left-hand-ends of the supporting rods2|6 are firmly clamped together by an arrangement comprising a fixture2l1 and a late 2|8 secured together by two rivets 2l9. Moreparticularly, the fixture 2|1 and the'plate 2|8 are respectivelyarranged rearwardly and for- Also the movable knife support 2|6comprises an arrangement including two plates 22l and 222 for securelyclamping together the intermediate sections of the two supporting rods2|6. More particularly, the two plates 22| and 222 are respectivelydisposed rearwardly and'forwardly of the two supporting rods 2|6 and aresecured together by a screw 223 extending therebetween and between thetwo supporting rods 2|6. The plate 222 also constitutes a first clampingjaw which cooperates with a second clamping jaw 224 to retain a knifeblade 226 therebetween. More particularly, the knife blade 226 isretained securely in place between the two clamping Jaws 224 and 222 bytwo screws 226 extending through aligned holes provided in the twoclamping jaws 222 and 224 and threading into aligned tapped holesprovided in the plate 22 More specifically, the knife blade 226 occupiesan inclined position, whereby the knife edge thereof extends through theslot 206 formed inthe base 200 and above the bottom wall of the paperchute 202. The movable knife support 2|6 is normally biased toward theright, as viewed in Fig. 7, by an arrangement comprising a coil spring221 extending between the fixture 2H and the right-hand side fiange 20|of the base 200. More particularly, the fixture 2|'| constitutes amarginal stop limiting the travel of the movable knife support 2|5toward the right due to the bias of the coil spring 221. When themovable knife support 2" occupies its fully retracted position to theright due to the resiliency of the coil spring 221, the knife blade 225occupies a position disposed toward the right and projecting through theslot 206 formed in the base 200, as clearly shown in Fig. 6. When theknife blade 226 occupies the last-mentioned position, the movable knifesupport 2|! occupying its fully retracted position toward the right, the

ribbon of paper stock fed through the guide chanwardly of the twosupporting rods 2|6 and the two rivets 2|9 extend therebetween andbetween the two supporting rods 2|6; thereby securely to clamp in placethe left-hand ends of the two supporting rods 2| 6. At this point it isnoted that the fixture 2| 1 carries a downwardly and rearwardlyextending lug 220 which cooperates with the upstanding dog I30 carriedby the arm 126 of the rocking lever I22, in a manner more fullyexplained hereinafter.

nel formed in the paper guiding structure across the slot 206 formed inthe base 200 into the paper chute 202 is not interfered with in any way.

The knife blade 226 is readily removable from the two clamping jaws 224and 222merely by loosening the screws 226. Preferably the knife blade226 is of razor blade" construction, whereby it may be readily removedand disposed of when it becomes'dull; anew knife blade 226 beinginserted therefor between the clamping jaws 224 and 222 and securelyclamped in place by tightening the screws 226.

In view of the foregoing description of the construction and arrangementof the paper cutting mechanism ii I, it will be readily understood thatthe movable knife support 2 I5 is normally biased by the coil spring 221to the fully retracted posi-. tion toward the right, as viewed in Fig.6, whereby the ribbon of paper stock may feed without interference fromthe paper guiding structure into the paper chute 202. In order tooperate the paper cutting mechanism I, it is only nec- .viewed in Fig.6, the ribbon of paper stock feeding through the paper guiding structureinto the paper chute 202 is severed in an obvious manner; whereby thesevered strip of paper stock is free to slide down'the paper chute 202into a suitable receptacle due to the action of gravity.

The paper cutting mechanism III is operated in a manner more fullyexplained hereinafter due to the cooperation between the downwardlyextending lug :29 carried by the fixture 2n and the upwardly projectingdog I30 carried on the Accordingly the base 200 is moved from the righttoward the left, as viewed from the front of the machine, while themovable wife support M5 is retained latched in a stationary position bythe cooperation between the dog I30 and the lug 220. This moyement ofthe base 200 toward the left eiiectively draws the knife blade 225across the slot 205 formed therein, whereby the ribbon of paper stock issevered in the manner explained above. 1

Referring now more particularly to Figs. 1, ll

and 12 of the drawing it is noted that the paper position testingmechanism H2 comprises a base plate 250 which is removably secured tothe subframe M2 or the machine I by means of a number of screws or thelike rearwardly or the casing structure we. Also the mechanism IIZcomprises electromagnetic structure including a It will be understoodthat when the carriage I03 of the machine I00 occupies its normalrighthand marginal stop position, as viewed from the front ofthe'machine I00, the roll of paper I60 carried by the paper supportingand guiding mechanism H0 engages the end of the rod 266,

- thereby to move the armature 253 of the paper.

i is attracted and moved toward the core .When the armature 253 is movedtoward the core position testing mechanism 2 toward the core 252.Further it will be understood that, when the winding 250 is energized,the armature 253 252.

252 the arm 260 carried thereby causes the in,- sulator 2M to controltheset of switch springs 262 for signaling purposes. 7

. 0n the other hand, when the carriage I03 oi 'the machine is moved awayfrom its right-hand marginal stop position, asviwed from the front ofthe machine I00, the roll of paper W0 carried by the paper supportingand guiding mechanism H0 disengages the end of the rod 20%,

whereby the set of switch springs 262 tends to move the armature 253away from the core 252 due to its resiliency; Similarly, when thewinding i is deenergized the set of switch springs 2B2 tends to move thearmature 253 away from the core 252. When the armature 253 is moved awayfrom the core 252 the set of switch springs 252- is controlled in. theopposite sense for 51gfield element .255, a core 252, an armature 253and a winding 255 carried by the core- 252; the field element 255 beingsecured to the base plate 250-by two screws 255. pivotally. mounted upona pivot .pin 25d carried by a bracket 25! which is in turn secured tothe field element 25i by a screw 250. Further thebase plate 250 carriesa plate 259 which is adapted to "support a removable housing, not shown,for. the mechanism H2. Further the armature 253 is provided with arearwardly extending arm 260 which carries an insulator 268 on the outerend thereof; the insulator ,zsl cooperating with a suitable set oiswitch springs 2B2 carried by the field element 2 5i,

Further a bar 250 is secured to the armature 253 by two screws 254and isprovided with an elongated slot 255 in the upper end thereof. The upperendof th: bar 203 carries a paper roll contact rod 256 which extendsthrough the slot 265 formed therein and is threaded into a tubularmember 25?. Also a lock nut 268 is threaded upon the rod 255. Thearrangement above de scribed permits ready adjustment of the rod 208 inthe vertical direction toward and away from the endo! the bar 253;, alsothis arrangement permitsready adjustment of the end of the rod 266toward and away from the bar 263, Accordingly the rod 208 may be readilyadjusted toward and away from the axis of the shaft I57 supporting theroll of :paper I00 in order to adjust the mechanism II2 to diflerentsizes of cores.

of spools upon which the roll or paper I60 is wound. Also the rod 200may be readily adjusted toward and away from the end of the paper rollI00 in accordance with the normal right-hand marginal stop position ofthe carriage I00 of the machine I00 as determined by-the position or theri ht-hand marginal stop H0 carried by the marginal stop rack H0.

The armature 2501s 7 naling purposes. Thus it will be understood that,when the winding 25% is energized or the roll of paper I engages the rod266, the armature 253 is moved toward the core 252; and that, when thewinding 25% is 'deenergized and the roll of paper I60 disengages' therod 266, the armature 253 is moved away from the core 252; whereby theset of switch springs 252 is'selectively controlled.

During the operation of the machine E00, when the carriage I08 thereofoccupies its normal right-hand marginal stop position, as viewed fromthe front of the machine M30, and there is ample paper stock upon thepaper roll M0, the rod 260 is engaged, thereby to move the armature 253toward the core 252. When the machine I00 is seized 'for use the winding25% is energized thereby to retain the armature 258 attracted toward thecore 252. Subsequently, after the complete operation of the machine we,the carriage I03 thereof is operated toward'its right-hand marginal stopposition. and the winding 250 is deenergized. At this time the armaquentreoperation.

ture- 250 remains in its. position adjacent the 0 core 252 only in theevent that the carriage 903 of the machine I00 is moved fully to itsright== hand marginal stop position andin the additional event thatthere is adequate paper stock upon the roll I00 in order to engage therod 266. Hence it will be understood that, at the conclusion of theoperation of the machine I00, in the event the carriage I03 thereof isnot returned completely to its right-hand marginal stop positionor thereis inadequate paper stock upon the roll I60, the rod 200 is not engagedand the armature 203 is moved away from the core 252; whereby a suitablesignal is controlled in order to indicate that one of the conditionsmentioned above exists and that the machine I00 is accordingly not inreadiness for subse- Again considering Figs. 1 and 10 of the drawings,it is pointed out that, in the machine I00, the ribbon of paper stockextends from the roll no rotatably supported by the shaft I51, forming apart of the paper supporting and guiding mechanism IIO, up through theguide channel formed between the supporting bracket I50 and theupstanding channel-shaped body I53 and then in a substantiallyhorizontal direction across the horizontal wall I54 to a horizontaltransversely extending paper guide 300 incorporated in the structure ofthe carriage I03. The ribbon of paper stock continues from the paperguide 300 between the platen roll I09 and a horizontal transverselyextending pressure roll 30I, incorporated in the structure of thecarriage I03, and thence around the platen roll I09 and between theplaten roll I09 and a horizontal transversely extending paper shield302. The paper shield 302 is suitably secured by a series of rivets 303to a paper guide 304 incorporated in the structure of the carriage I03.Also it is noted that the paper shield 302 has an elongated slot 305formed therein, whereby the surface of the paper disposed below theslot,305 is adapted to be contacted by the type levers I04. The tensionexerted upon the ribbon of paper stock feeding from the roll I60 andbetween the platen roll I09 and the pressure roll 30I may be adjusted bytightening or loosening the thumb screw I18 in order to cause the leafspring member I'II to exert more or less pressure upon the ribbon ofpaper stock. as it passes over the knee disposed between the upstandingchannel-shaped body I53 and the horizontal wall I54, in the mannerpreviously explained. After the ribbon of paper stock passes between thepaper shield 302 and the platen roll I09 it extends into the paper,guiding structure, forming a part of the paper cutting mechanism III andincluding the bottom wall 201' and the top wall 209, and over the slot206 formed in the base 200 into the paper chute 202. The strip of theribbon of paper stock,extending beyond the slot 206, formed in the base200, and into the paper chute 202 may be readily severed by operatingthe paper cutting mechanism III, in the manner previously explained,whereby the severed strip of the ribbon of paper stock may slide downthe downwardly and rearwardly inclined paper chute 202 into a suitablereceptacle. At this point it is noted that the guiding surfaces of thepaper supporting and guiding mech-' anism I I0, as well as the guidingsurfaces of the paper cutting mechanism II I, are highly polished inorder to minimize the frictional drag exerted upon the ribbon of paperstock passing thereover. Also the interior surface of the paper chute202', forming a part of the paper'cutting mechanism III is highlypolished, whereby the strip of severed paper stock may slide down theinclined paper chute 202 due to the action of gravity and be received bya suitable receptacle.

At this point it is noted that both the shaft I 51, forming apart of thepaper supporting and guiding mechanism H0, and the paper chute 202,forming a part of the paper cutting mechanism III, are disposedrearwardly of the rear wall of the subframe I02. More particularly, thearms 159 of the paper supporting and guiding mechanism IIO, whichsupport the shaft I51, extend through a rectangular opening 306 formedin the rear wall of the subframe I02; the opening 306 formed in the rearwall of the subframe I02 extending transversely thereacross a distancesufficient to accommodate the normal travel of the carriage I03 of themachine I00. The paper chute 202 of the paper cutting mechanism IIIextends over the rear marginal edge of the main frame I0 I whereby thereceptacle which is adapted to receive the severed strips'of the ribbonof paper stock may be disposed rearwardly and clear of the machine I00.

- Considering now the operation of the tabulating mechanism incorporatedin the machine I00 in conjunction with the operation of the papercutting mechanism I II, reference is again had to Figs. 1 to 3,inclusive, and 6 to 8, inclusive,

. of the drawings. At the conclusion of a complete printing operation ofthe machine I00 the carriage I03 occupies a position displaced from theright-hand marginal stop position thereof, as viewed from the front ofthe machine I00, corresponding to one space beyond the last characterprinted upon the last line of the section of paper stock appearing inthe slot 305 formed in the paper shield 302, as will be readily undertheprinting matter appears is fed from between the paper shield 302 and theplaten roll I09 through the paper guiding structure, forming a part ofthe paper cutting mechanism III, and

beyond the slot 206 formed in the base 200 and into the paper chute 202.At this time the carriage I03 of the machine I00 occupies its normalright-hand marginal stop position and the tabu.. lating operating magnetis energized, whereupon the carriage I03 is automatically moved from itsright-hand marginal stop position to its left-hand marginal stopposition.

More particularly, when the tabulating mechanism incorporated in themachine I00 is thus operated, the rocking lever I 22is rotated in theclockwise direction about the screw I23, as viewed in Fig. 2, by theoperation of the tabulating lever II 8, and the tabulating lever H8 isrestrained in its operated position by the latch I34, in the mannerpreviously explained. When the rocking lever I22 is rotated in theclockwise direction about the screw I23, as viewed in Fig. 2, the dogI30 carried by the arm I26 thereon is moved forwardly toward the platenroll I09 and into such a position that it is disposed in the path ofmovement of the downwardly projecting lug 220 formed.

on the fixture 2II carried on the left end of the movable knifesupport-2I5, as shown in Fig. 6. As the carriage I03 moves toward theleft, the lug 220 hangs upon the dog I30, whereby further movement ofthe knife lupport 2| 5 is arrested. However, the carriage I I3 continuesto move toward the left, whereby the remainder of the cutting mechanismHI, including the base 200, is moved therewith. When the base 200 isthus moved toward theleft, while the knife support 2I5 is held in astationary position, the knife blade 225 is effectively drawn throughthe slot 206 formed in the base 200, whereby the section of the ribbonof paper stock disposed beyond the slot 206 and in \the paper chute 202is severed. The last-mentioned section of the ribbon of paper stockincludes the matter printed thereupon due to the last operation of themachine I00. Accordingly, the severed strip of the ribbon of paper stockincluding the printed matter, due to the last operation of the machineI00, comprises a ticket which slides down the paper chute 202 into asuitable receptacle.

Subsequently, when the carriage I03 is completely returned to itsleft-hand marginal stop position the tabulating lever H8 is released dueto its movement with respect to the pin H9; whereupon the latch I34rides from behind the abutment I36 provided on the left-hand end of thetabulating lever H8, in the manner previously explained. At this time,when the tabulating lever- H8 is released, the rocking lever I22 isrotated in the counterclockwise direction about the screw I23, as viewedin Fig. '2, by the coil spring I21, whereby the upstanding dog I30provided on the arm I26 disengages the downwardly extending mg 220carried by the fixture 2H. forming a part of the movable knife support215. When the dog I30 disengages the lug 220 the knife support 2l5 isreleased and is-retumed toward the left to its normal position, as shownin Fig. 6, due to the resiliency of the spring 2217. At this time, thepaper cutting mechanism III has completed its operation and occupies itsnormal position. The return and line space operating magnet is thenenergized in order to cause the carriage M3 to be returned to its normalknife normally movable with said carriage and slidably supported forlateral movement with respect thereto, and means for arresting move-,ment of said slidably supported knife with re-=-- spect to saidcarriage and for effecting movement of said carriage, whereby thesection of said base member carried by said carriage and having alaterally extending slot formed therein across which the section of saidpaper stock upon which the printing appears is fed, a knife normallymovable with said carriage and slidably mounted thereon for, lateralmovement in s id slot, and means for restraining further move ent ofsaid knifewith respect to said carriage-to efiect latright-hand marginalstop position. At this time the machine it is completely released Landis available for further use for the next printing operation. v

The operation of the paper position testin mechanism H2 incident to theoperation of the machineiflt is fully described above, and in theinterest of brevity is not again repeated. 1
